Title: Improvements in or relating to television and like signalling systems and signal transmitters
IPC: H04N11/12
Filed: 1957-03-14
Abstract: 813,096. Multiplex radio signalling. PHILLIPS ELECTRICAL INDUSTRIES Ltd. March 14, 1957.[March 14, 1956], No. 8461/57. Class 40 (5). In an electric signalling system of the type in which two television or like information signals are transmitted simultaneously but independently as modulation of a sub-carrier which modulates a main radio-frequency carrier and the information signals are added before modulation is effected, to correcting signals for the purpose of reducing the effect of cross-talk, the correcting signals are the same for each of the information signals, and are proportional to the product of the information signals. The system is similar to that described in Specification 776,989, but it is shown that a close approximation to the desired correction, with a simplification of the apparatus, is obtained with correcting signals satisfying the above conditions. Provision may also be made for gamma correction in a television transmitting system. In the embodiment described, signals f 1 ,f 2  originating from two television cameras are first applied to two units 10 and 11 respectively which operate as gamma correctors and supply signals f 1 1/γ and f 2 <SP>1</SP>/γ to a unit 12 having an output proportional to the product of the incoming signals amplified by a suitable factor K to provide the correcting signal. The correcting signals are applied to mixers 13, 14 which also receive inputs from the units 10, 11 respectively and provide outputs # 1  = f 1 <SP>1</SP>/γ + Kf 1 <SP>1</SP>/γf 2 <SP>1</SP>/γ and # 2  =f 2 <SP>1</SP>/γ+ Kf 1 <SP>1</SP>/γ f 2 <SP>1</SP>/γ. These signals are applied to modulators 15, 16 and multiplied by phase-displaced functions g 1  = 1 + 2 cos # o t and g 2  = 1 - 2 cos # o t, where # 0  is the angular frequency of the sub-carrier, as described in Specification 776,989. The outputs of modulators 15, 16 are combined at 17 and applied via a filter 18 to a modulator to modulate the main carrier.

Title: Improvements in and relating to arrangements for preventing arcing in inductive electric circuits
IPC: H01H9/54
Filed: 1939-03-16
Abstract: 526,456. Sparking-preventing in switches. HILL, C. J. W. March 16, 1939, No. 8467. [Class 38 (v)] Circuits containing inductive devices are sparklessly opened by shunting the winding by a circuit comprising a condenser and resistance in series and of such magnitudes that the whole simulates a pure resistance. The magnitude of the resistance in the shunt circuit is made equal to the inherent resistance R of the inductive winding, the condenser being of such capacity C that L = CR<2>. To compensate for variations in the effective resistance of the winding, a large swamping resistance may be arranged in series with it, the value R in the above expression then equalling the sum of the inherent and swamping resistances. This arrangement enables a smaller condenser to be used.

Title: Improvements in or relating to the separation of glycosides and aglycones from strophanthus sarmentosus
Inventor: CALLOW ROBERT KENNETH
IPC: A61K36/00
Filed: 1951-04-13
Abstract: Glycosides are separated from the powdered seeds of Strophanthus sarmentosus by extracting the seeds with a lower aliphatic alcohol (with or without water), evaporating the extract until the residue is resinous, forming an aqueous extract of this residue and treating this extract with a hydroxylic solvent which is not wholly miscible with water; two solutions are thereby obtained which may be treated to recover the constituents.  The material may at any stage be submitted to acid hydrolysis to obtain the free aglycones.  The seeds are preferably defatted (with carbon tetrachloride) before and/or after the initial extraction with the aliphatic alcohol, which may be methanol, ethanol or n-butanol.  The partition is preferalby carried out in a countercurrent manner to facilitate fractionation of the constituents into the two phases.  The aqueous phase yields sarmentosides A and B and the solvent phase (after hydrolysis) yields sarmentogenin.  An example is given of the process using n-butanol as the hydroxylic solvent.  Specification 650,380 is referred to.
